Montgomery was active in the civil rights movement, serving as a bodyguard to King during the famous 1965 Selma to Montgomery march.

Amelia Montgomery said the heels of the shoes and the tie her husband wore on the Selma march will be part of the permanent collection at the new National Museum of African American History and Culture in Washington when it opens on Sept. 24.

Montgomery was awarded the Congressional Gold Medal in 2007 after President George W. Bush signed a law awarding the distinction to all original Tuskegee Airmen.
